To elucidate the role of A1, a new member of the Bcl-2 family of apoptosis regulators active in hematopoietic cell apoptosis, we established mice lacking A1-a, a subtype of the A1 gene in mice (A1-a-/- mice). Spontaneous apoptosis of peripheral blood neutrophils of A1-a-/- mice was enhanced compared with that of either wild-type mice or heterozygous mutants (A1-a+/- mice). Neutrophil apoptosis ...

The research focused on determining the economic value of a selected collection 20 shrubs from wild-growing population Mahonia aquifolium (Pursh) Nutt. Arboretum Mlyňany and Nitra region. By morphological analysis, we determined weight fruits 0.18–0.50 g, height 5.57–13.22 mm, width 0.98–11.00 number seeds 1.67–5.30 pcs. content macro- microelements was found in leaves. M. samples are very valu...

The Lie symmetry method is applied to derive the point symmetries for N-dimensional fractional heat equation. We find that numbers of and brackets are reduced significantly as compared integer order all dimensions. In fact linear equation number solution equal product space dimension, whereas case, it half on dimension. algebras equations mentioned using subsequent computations by inspection. I...

Let Mn be the set of n × n complex matrices, and for every A ∈ Mn, let Sp(A) denote the spectrum of A. For various types of products A1 ∗ · · · ∗ Ak on Mn, it is shown that a mapping φ : Mn → Mn satisfying Sp(A1 ∗ · · · ∗ Ak) = Sp(φ(A1) ∗ · · · ∗ φ(Ak)) for all A1, . . . , Ak ∈ Mn has the form X → ξS−1XS or A → ξS−1XtS for some invertible S ∈ Mn and scalar ξ. The result covers the special cases...
